This is another dumb idea, but... 

Say we allowed the syntax

    method1(args)  method2(args)

method2 would have to return a proc object.

Then we could do something like


  def into(anArray)
    proc { |i| anArray << i }
  end


  (1..10).each into(a = [])

Ideally I'd like the whole expression to return the array, but I can't 
see a tidy way to do that.
